> ct_query failed. hw_path = 8/4/1/0

This is the problem. The disk at 8/4/1/0 has a problem that caused the panic. Normally, this would be handled with syslog and console errors but if this disk failed in an area with swap, the kernel can't handle a virtual memory area as cleanly as simple data files.
